Pattern direction by runway

Runway	Pattern	Heading	Pattern altitude
03	Left traffic	025° mag	1,900 ft MSL (≈1,000 AGL)
21	Left traffic	205° mag	1,900 ft MSL (≈1,000 AGL)
14	Left traffic	139° mag	1,900 ft MSL (≈1,000 AGL)

No pattern altitude is published for KMIE; the figure above is the AC 90-66B 1,000 ft AGL convention for propeller aircraft, rounded to the field. Turbine aircraft normally fly 1,500 ft AGL. Headings are the runway alignment; downwind is the reciprocal.

Flying the pattern at KMIE

Delaware County Johnson Field is towered, working 120.1. Contact the tower before entering the surface area and fly the pattern you are assigned — the directions below are the charted default when no instruction is given.

All ends are left traffic, which is the FAR 91.126 default — turns to the left unless the field charts otherwise. The full entry procedure is here →

Frequently asked

What is the traffic pattern altitude at KMIE?

Delaware County Johnson Field has no traffic pattern altitude published in the FAA NASR data. The AC 90-66B convention for propeller aircraft is 1,000 ft AGL, which works out to roughly 1,900 ft MSL (≈1,000 AGL) here — but confirm it against the Chart Supplement before you fly, since a field can have a non standard pattern altitude that NASR does not carry.

Does KMIE have right traffic?

No. All 4 runway ends at Delaware County Johnson Field use standard left traffic, so no right pattern is charted here.

Do I fly a standard pattern at KMIE?

Delaware County Johnson Field is towered (120.1), so the pattern shown here is the charted default — but the controller's instruction overrides it. Expect straight in approaches, base entries and midfield crossings as traffic dictates.

More about KMIE

Pattern direction and alignment are drawn from the FAA NASR (28-day cycle); the diagram is generated, not an FAA chart. Pattern altitude is shown as published where NASR carries one, otherwise as the AC 90-66B 1,000 ft AGL convention. For planning and education only; always verify against the Chart Supplement.
